Footwear
With a variety of high-performance compounds for footwear applications, Aurora Material Solutions is a valued partner to the footwear industry. Our innovative line of AuroraFlex™ flexible PVC, SBS and SEBS, and TPR compounds are used for soling, mid-soling, boots and many other applications.
Unlike rigid PVC, AuroraFlex flexible PVC is a cost-effective alternative to our thermoplastic elastomers. These compounds provide flexible PVC from 35A to 95A Shore A durometer* to semi-rigid, with specific gravities ranging from 1.15 to 1.65. We use various types of compound additives to promote plasticity and flexibility to meet specific needs, such as renewable non-phthalate, improved low temperature tolerance and biocides. When you’re looking for a compound that offers high-abrasion resistance and excellent processing properties, AuroraFlex SL is designed to produce longer-lasting materials, with no tearing.
AuroraFlex SBS and SEBS compounds utilize multiple TPE chemistries to impart high-performance properties for durability and easy processing. There are hundreds of color options, and all of these compounds are offered in both molding and extrusion grades. TPE options are available as low as 10A* up to 50D durometer hardness. Some of our TPEs are offered in clear, as well as oil free grades.
AuroraFlex TPR (thermoplastic rubber) compounds are formulated using styrene-butadiene-styrene (SBS) or styrene-ethylene/butylene-styrene (SEBS) block copolymers. These materials have many of the same properties as vulcanized rubbers, but can be molded and extruded using conventional thermoplastic process equipment. Thermoplastic processing provides advantages over vulcanized, thermoset rubbers, which are processed using a slower and more costly curing process. Most of our TPR formulations are 100% recyclable and are RoHS compliant.
Our team will also work with you to complete the formulation, making sure to find fillers that meet your specific application needs.
* NOTE: Durometer hardness is measured with a calibrated durometer using the Shore Type-A scale in a room of consistent temperature. The indenter is inserted for 15 seconds to determine if it passes the ASTM D2240-Durometer Hardness test for the desired durometer.
